SPS and multi-PDSCH configuration and DCI for multiple TB case

Abstract

A user equipment (UE) may receive and decode multiple types of transport blocks. The UE may receive, via the transceiver, a downlink control information (DCI) that indicates at least first transmission parameters for a first type of transport block for the UE and second transmission parameters for a second type of transport block for rate-splitting with a second UE. The UE may receive, via the transceiver, the first type of transport block during a first physical downlink shared channel (PDSCH) occasion based on the first transmission parameters. The UE may receive, via the transceiver, the second type of transport block based on the second transmission parameters and a third type of transport block based on third transmission parameters during a second PDSCH occasion.
